120107-80-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 120107-80-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,1,0 and 7 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 120107-80:
(8*1)+(7*2)+(6*0)+(5*1)+(4*0)+(3*7)+(2*8)+(1*0)=64
64 % 10 = 4
So 120107-80-4 is a valid CAS Registry Number.
